Charlotte, NC area: hate on OP, houses, boats & hoes

Just reading on this 300BLK, sees like the way to go if I go with a short barrel, says 5.56 looses a lot of energy (plus has a fireball of unburned powder in short barrels). Only downside seems to be ammo cost....

 

If you get loads for 5.56 for SBR applications, they will cost more than typical ball green tip ammo. The typical ball ammo really shines out of a 16+ inch barrel due to the velocities the bullet yaws and fragments at. In order to get this performance out of an SBR, you have to start manipulating the powder and weight of the round.

This is what I would do if I was in your shoes. Keep you 5.56 upper and buy a 300 BLK upper. There you have your bases covered for range and SBR on the same platform.

 

Do you mean keep the 5.56 upper and buy a new 300BLK UPPER? That's what I intend to do. I have a ton of 5.56 ammo in case SHTF, so keeping that upper makes sense.

 

Yea, sorry. I edited the post

 

Cool, thanks. I like this plan very much.

 

it's good plan. The 300 BLK performs great suppressed as well. I see a can in your future bud.

 

Yeah, haha I kinda expect that too.

 

Just to be clear, I do not need new BCG or CH right? I can just get the upper?

Only thing you will need is the upper. No BCG or CH as they will work with the casing of the 300 BLK. You can even use your same mags.

 

The 300 BLK is the same casing as 5.56/2.23. It’s just cased to a 30 caliber round instead of 22 caliber.

 

I would strongly suggest to use a completely different colored or brand of magazine for the two calibers...you don't wanna mix them up.

 

This is a good tip. I use tape.

 

Mags are the same though right? So don’t need to worry about it if I don’t have a built 5.56 right?

 

Yes mags are the same. Just don't want to mix up 5.56 rounds with 300 rounds when shooting from different uppers. A 22 caliber barrel would not like a 30 caliber round going down it.

 

Probably wouldn’t get very far...

 

The bolt won't close putting 300 down 556. Your problem exists going the opposite putting 556 down the throat of a 300 blk barrel

 

You sure?

Nice. Time to start looking for a can.
